Hi, I've been looking at ways to get the most out of the standard HW-supported delta encoding and Delta modulation has some simple equations that could be used to construct the perfect low-pass filter and limiter, I'm just missing what the exact step size of delta encoding is on the NES. I have a hunch that it is not uniform along the 64 steps given how the APU2 channels are mixed but an average would probably work fine here. This could achieve the best middle-ground of not having any slope overload (or very little), which in my experience is a must for musical bits. But I still want to try working with the highest dynamic range possible to reduce granular noise. This balance between the two noise types is exactly what I'd try to avoid and prefer granular noise over slope overload. It also makes me question how much different consoles and signal transmission methods (composite vs. RF) can do to low-pass the audio enough to dim the granular noise that is there.
Thank you all for any tips or insight!
